2 Overview
2.1 General Characteristics
The iCE
3
(iQuest Circuit Extender) has been designed as a cost effective, low power, self-contained circuit
extender to enable communication with equipment over a wireless (GPRS) network connection. Typical
devices that the iCE
3
can be used to interface with include dataloggers, PLCs etc.
The unit is based on the Wavecom® M1206/M1306 “Fastrack” GSM/GPRS modem. iQuest have taken the
standard issue modem, modified it internally and developed a comprehensive software application that
resides within the device. This application provides the GPRS network link management, data transfer and
configuration view/edit functionality.
The iCE
3
unit comes standard with a d.c power lead and a host device (RS232) cable pre-wired for one of
three different host device types (see Section 7). The SMA antenna connector allows the use of a small
stubby antenna (optional accessory) or alternatively, a coaxial cable to a higher gain external antenna for
use in areas where signal strength is lower.
2.2 Typical Applications
The iCE
3
can be used in a number of applications, including:
- GPRS circuit extension to third party devices
- GPRS telemetry
- GPRS / RS232 serial gateway to multi-drop networks
The iCE
3 provides a very effective means for migration of legacy dialup telemetry networks to more cost-
effective wireless IP communications over GPRS. By simply replacing existing dialup modems with an iCE
3
,
you can have virtually any logger type telemetered over GPRS. If you are using a HydroTel telemetry
system, the iCE
3
can be configured to call-in and be downloaded using a dynamic IP address which further
simplifies the deployment. See Section 2.4.3 for more details.
